FLY SCREEN FOR WINDOWS.

Application filed July 13,

To aZZ whom it may concern:

Be it known that I, EUSTACHIO GUARDI- ANI, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certainnew and useful Fly Screens for Windows, of which the following is a specification.

My invention relates to window screens and more particularly to an adjustable screen to fit beneath the raised lower sash of a window. V

The purpose of my invention is .to'provide an improved screen of the character indicated adapted to easy and inexpensive manufacture and to, adequately meet the needs of service. n

A further purpose is to provide the screen with a safety device so that if a child leans against it there may be no danger of the screen suddenly giving way and 0f the child possibly falling through the window.

A further purpose is to have this safety device comprise support against the bottom of the raised lower sash at the top and support against the window strip in front of the screen at the bottom. 1

A further purpose isto providea pair of intersliding screensadapted to. fit beneath a raised lower sash with improved connection, between the mesh and frame of each screen, in which the mesh is clamped to advantage by the frame parts of the screen.

Further purposes will appear in the specification and claims.

I have preferred to illustrate my invention by but one type, selecting a form that at once well illustrates the principles of my invention and adequately meets the needs of actual service.

Figure 1 shows my invention in front elevation.

Figure 2 is a section through the line 2-2 of Figure 1.

Figure 3 is a detail section to enlarged scale through the line 33 of Figure 1. Figure 4 is a detail section to enlarged scale through the line 44 of Figure 1..

Figure 5 is a detailed section to enlarged scale throughthe line 5-5 of Figure 1.

Figures 6, 7, 8 and 9 are broken end elevations at the respective corners of Figure 1 but to slightly enlarged scale, and illusmating channels members and by an inward hook 26 from screen slidably hooking over 1922. Serial No. 574,706.

trate the construction of the frame at the outer corners. V

In all drawings like numerals refer to like parts.

Referring to'the drawings anddescribing in illustrationand not in limitation,-

My improved screen comprises outerand inner screens, 15 and 16 respectively, that interslide to fit between the vertical slide Ways'17, 18 of 20,21 of the inner screen sliding inthe 22, 23 of the outer screen. preferred to show both the channel I have than the rails upon either outer'or inner screen, or a combination of these, as it, makes a very neat assembly of the parts.

Prior to my invention, the'convenience of the sliding screens that fit beneath the raised port the screen from displacement outward by an upward projection 24 from'the intermediate side 25 of the inner screen extending it partially-across thebottom of the raised sash '19, thus preventing the top of the screen from yielding to an outward push,

the interthe inner the window mediate side of thebottom of strip 27 in front of the screen.

Normally the sides of the screen next the window are supported along their whole the raised sash 19, rails upon the outer screen and both the rail members upon the inner screen, rather,

length, and consequently at top and bottom,

by the vertical slide-ways 17, 18, of the sash, but experience has shown that in use this type of'screen very frequently works w free from the slide-ways, and in view of this I also preferably provide upward projections the sides of the 28, 29 respectively from screens adjacent the window. These projec tions, like projection 24, extend partially across the bottom and support the top corners of the screen from yielding to any outward push; likewise at the bottom I preferably provide the inward hooks 30, 31 from near the lower corners of the screen to hook over the window strip 27.

to place The hooks 31, 31 and the upward projections 28, 29 are suiliciently spaced from the sides to clear the slide-ways 17, 18 of the sash. V

in order to avoid undue motion of the individual screens after they have been fitted i provide the hook ot the outer screen and one of the hoolrs of the inner screen, with screws 32, 33 adapted toclamp the respective screens to the window strip 27, as seen in Figure 5. V

Mv invention comprises not only these safety devices but also the improved connection oi the mesh to the frame of the screens.

lhdvertical sides 35 respectively at the slide-ways 17, 18 are ot wood and are saw-cut longitudinally at 36, the mesh 37 being inserted into the saw-cuts and clamped there by nails 3.8.

At the intermediate vertical of theinner and outer screens meslrbetween wooden strips all, as and metal angles 43, l i as bestseen in Figure 8, and on the inner screen i extend the liattened side 45 of the angle above the screen to form the supporting projection side fian e of the angle in FigureB supports the angle, and hence the fastening screws, against thestrip as, to talrcthe stra n of the sides 39,

' mesh toward the. left in that figure.

Along the channel and rail members of the individual screens 1 make connection to the mesh as best seen at 46, 470 5 Figure 5. The channel is nearly all made of wood, in two parts 48, 49 and these parts are nailed together. with the mesh between them. In Figure 5, 50 is the outer edge of the angle 44 of the outer screen, the other side of the angle being cutaway at the end of the strip 42, best seen in Figure 3. V

'l. he rail member comprises a wooden member51, preferably substantially symmetrical, upon one side 52 of which the mesh is clamped by a metal flat or strip 53.

The vertical sides 3%, 35 are conveniently provided with handle cuts 54,55 as seen in Figures 1 and 4t.

The framing between the vertical and 7 horizontal members of the individual screens is shown in Figures 6 to 9. Between a vertical member and a channeled member the framingis constructed as seen in Figures 6 and 7, the vertical member being notched at 56, 57 and plowed at 58 to fit the channel which is cut away at the side for the tenon the vertical member.' A vertical member and a rail member are halt notched as shown in Figures 8 and 9, the rail portion of the rail member being cut away and the vertical member suitably notched to lit.

In'view of my invention, variationsvand modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art and I claim t clamp the all such variations and modifications in so far as they fall within the reasonable sp1r1t and scope or" my invention.
